An international research team has developed inks made of graphene-like materials for inkjet printing. New black phosphorus inks are compatible with conventional inkjet printing techniques for optoelectronics and photonics.

Since the discovery of the Nobel Prize winning material graphene, many new nanomaterials promise to deliver exciting new photonic and optoelectronic technologies. Black phosphorus is a particularly interesting post-graphene nanomaterial for next generation photonic and optoelectronic devices. Yet despite remarkable performance in the lab, practical real-world exploitation of this material has been hindered by complex material fabrication and its poor environmental stability. "Our inkjet printing demonstration makes possible for the first time the scalable mass fabrication of black phosphorus based photonic and optoelectronic devices with long-term stability necessary for a wide range of industrial applications," tells Professor Zhipei Sun at Aalto University in Finland.
